Heavy-duty 12 x 80mm Tek Screw into Steel (50 Pack) designed for fixing industrial fibreglass roofing sheets to steel structures. Requires 32mm Weatherlok Washer (sold separately) for a watertight, long-lasting seal.
The 12 x 80mm Tek Screw into Steel (50 Pack) is a high-strength roofing fastener engineered for securely fixing industrial fibreglass roofing and wall sheets to steel purlins and frames. Built to handle Australia’s tough conditions, these screws provide superior holding power and long-term weather protection.
Featuring a self-drilling Tek point, each screw cuts cleanly through fibreglass and steel without the need for pre-drilling, making installation fast, precise and efficient. The sharp drill tip and coarse thread ensure maximum pull-out strength, while reducing the risk of over-tightening or sheet damage.
When paired with a 32mm Weatherlok Washer (sold separately), this fixing system delivers a tight, watertight seal that prevents leaks, corrosion and vibration around the fixing point. Manufactured from high-grade, corrosion-resistant steel, these screws are ideal for industrial, rural and commercial roofing applications, offering exceptional durability and ease of use.
